This is a faithful photographic reproduction of an original two-dimensional work of art. The work of art itself is in the public domain for the following reason:
Public domain This image (or other media file) is in the public domain because its copyright has expired.

This applies to Australia, the European Union and those countries with a copyright term of life of the author plus 70 years.

Dialog-warning.svg You must also include a United States public domain tag to indicate why this work is in the public domain in the United States. Note that a few countries have copyright terms longer than 70 years: Mexico has 100 years, Colombia has 80 years, and Guatemala and Samoa have 75 years, Russia has 74 years for some authors. This image may not be in the public domain in these countries, which moreover do not implement the rule of the shorter term. Côte d'Ivoire has a general copyright term of 99 years and Honduras has 75 years, but they do implement the rule of the shorter term.
This file has been identified as being free of known restrictions under copyright law, including all related and neighboring rights.

The official position taken by the Wikimedia Foundation is that "faithful reproductions of two-dimensional public domain works of art are public domain, and that claims to the contrary represent an assault on the very concept of a public domain". For details, see Commons:When to use the PD-Art tag.
This photographic reproduction is therefore also considered to be in the public domain.

Please be aware that depending on local laws, re-use of this content may be prohibited or restricted in your jurisdiction. See Commons:Reuse of PD-Art photographs.
